Eventually, fresh water leached out most of the salts that helped form the bonds that stabilized this material. In particular, quick clay deposits are frequently associated with landslides triggered by natural or man-made events. Examples of such landslides in the Trondheim region are numerous, with Gregersen O (1981) The quick clay landslide in Rissa, Norway.

The Lemieux landslide photo (left) of an earlier unstable clay soil or quick clay landslide is from the Canadian Department of Natural Resources. The May 2010 Times article explained that because the unstable clay formed in salt water the molecular structure of its particles is unstable (compared with clays formed as layers in fresh water).

At least two persons were killed in the landslide. The slide measured 2300 feet by 984 feet (700m by 300m). The collapse injured at least 10 people with one seriou Quick clay landslides have caused a large number of natural disasters in Norway. These have resulted in loss of human lives and major damage on property, roads, railways, and infrastructure.

Highly sensitive postglacial marine clays, termed quick clays, represent a risk for large retrogressive or progressive landslides such as the well-documented

One person died whilst 13 farms; 2 home 2021-01-02 · The exact cause of the landslide remains unknown. However, the quick clay ground under the affected area of Ask is known to be of high-risk for landslides. Quick clay is generally stable but when Quick clay may depart from its stable state due to multiple triggering factors (overloading, erosion, rainfalls, slope undercutting, earthquakes etc).

When daylight came at around 9 o`clock AM, some 20 buildings was down in the quick clay or on their way down the some 700 meters long and 300 meters broad landslide. 2021-01-02 · Quick clay is a sort of clay found in Norway and Sweden that can collapse and turn to fluid when overstressed. The authorities have banned all aircraft from the disaster area until 3pm (14:00 GMT 2.1 Essential facts about quick clay and quick-clay slides 9 2.2 The 1978 Rissa landslide, Sør-Trøndelag county 11 2.3 The 1996 Finneidfjord slide, Hemnes municipality, Nordland county 14 2015-04-30 · The quick clay exists as layers or planes in clay sediments with normal sensitivity, but in many places the entire clay stratum is comprised of quick clay (Lindskog, 1983). Our test site ( Fig. 1 ) is about 7 km north of the town of Lilla Edet, where the Göta landslide occurred in 1957. The quick-clay landslide in Verdal, where a total of 116 people perished in 1893, is also well documented (e.g. Walberg 1993).

One person died whilst 13 farms; 2 homes; a cabin and a community centre were taken by the clay masses. Five to six million cubic metres of clay collapsed from an area of 330,000 m2 leaving a 1.5 kilometre slide face.

2021-03-25 · The quick clay ground under the affected area of Ask is known to be at high-risk of landslides. Just before Christmas, a smaller landslide occurred a few kilometres further north but neither buildings nor people were affected. Quick clay is generally stable but when the structure is disturbed, the clay can liquify.

quick clay slides occur in marine clays that have an unstable structure. Disturbance of that structure can cause a massive reduction in strength, which then destabilises the slope allowing failure on even low slope angles.
